Blue land crab

Blue land crab (Cardisoma guanhumi) — field identification starting point: a broad-bodied crustacean with a hard carapace, five pairs of walking appendages and the first pair modified as claws. Confirm the exact species against the approved photo and scientific-name biology reference.

Common crab size is best judged by carapace width; many species here are roughly 3–8 in across.

Large crabs can exceed 8 in carapace width depending on species.

Many bivalves filter plankton; grazing snails eat algae/biofilm, while some mollusks are predators/scavengers.

Usually attached, buried or slow-moving on the bottom; distribution follows substrate, salinity and water quality.

Found in Puerto Rico. Start in the documented habitat and substrate for this species, then narrow the search using depth, current, structure and food activity. Habitat reference: Habitat: rocky bottom and mangrove.

Habitat: rocky bottom and mangrove.

Bottom-dwelling shellfish occur on sand, mud, seagrass, reef or hard substrate depending on species.

Search only legal collection areas and depths where the bottom can be inspected safely; closures and sanitary status matter more than a fishing depth number.

Water: marine. Habitat: rocky bottom and mangrove.

Collect only during open legal/sanitary periods.

Use daylight/visibility and safe tide conditions unless local rules and experience support another approach.

Low water or low current can improve access/visibility, but never enter exposed reef, surf or mudflat conditions unsafely.

Choose sea state, wind and visibility that let you hold position and handle the fish safely. Avoid treating rough weather as a feeding advantage.

Fish scraps, oily baitfish pieces or commercial crab bait are common in traps where traps are legal.

Not applicable.

Gloves, lawful crab gear, bait, measuring device if required and secure container.

Hook-and-line is not the default method; traps, dip nets or hand capture may be used only where legal.

Not applicable.

Not applicable.

Set baited gear in good bottom habitat and tend it often.

Let it go quickly if you're not keeping it.

Good eating — a common food fish where it's caught. Purge land crabs on clean food for several days and cook thoroughly; check local seasons.

Good table fare when bled, iced and cooked fresh.

Safety first: Claws can pinch or cut. Keep fingers away from the claws and control from a safe position. Keep live or freshly harvested crabs cool and clean according to food-safety guidance. Handle claws and sharp shell edges carefully; rinse exterior debris, cook or process promptly, and avoid cross-contamination from raw shellfish.

Cook crab thoroughly until the meat is firm and opaque and the animal/product has reached a safe cooked state. Keep cooked crab separate from raw shellfish and refrigerate leftovers promptly.

Claws can pinch or cut. Keep fingers away from the claws and control from a safe position.

Rules: Blue land crab / juey terrestre: Closed July 15 through October 15. Capture and possession are prohibited year-round in DRNA protected natural areas. Regulation 7949 and DRNA educational material state that recreational capture requires a permit, but the current public recreational application/purchase path was not verified in DRNA’s forms catalog; confirm directly with DRNA before harvesting. Closed July 15 through October 15. | Blue land crab / juey de tierra — Puerto Rico: 2.5 in carapace width minimum. Current DRNA Juey Común guidance confirms a 2.5 in minimum carapace width, recreational permit requirement, the recurring July 15–October 15 closure, and year-round capture/possession prohibition in DRNA protected natural areas. Destructive digging tools are prohibited. | Juey Común recreational permit — operational status unclear: Written DRNA material says a recreational permit is required, but this review did not locate a current public recreational application or purchase path. The public Juey-specific VS-08 form concerns importation/sale of live crabs, not ordinary recreational capture. Confirm directly with DRNA before harvesting.

Avoid needless kills and follow protected-species, area and season rules.
